CARDING-ENGINE.

Specification of Letters Eatent.

Eat-tented Feb. 1?, i @314,

b aZZ whom it may concern Be it known that I, PATRICK L. MoBnios, acitizen of the United States, residing at Gorhani, in the county ofCumberland and ttate of Maine, have invented a certain new and usefulImprovement in Caroling-Engines, of which the following is aspecification.

This invention relates to carding engines and consists in thecombinations and devices hereinafterdescribed and claimed.

Cording engines have hitherto usually in cluded a main cylinder or swiftarranged between the feed-rolls and doiier-comb or other means forremoving the fibrous materials from the card. Around the circumferenceof such main cylinder or swift are placed a plurality of smallercylinders, workers or carding rolls, the teeth of the card-clothing onsaid workers being arranged pointto point with the teeth of the maincylinder, for the purpose of removing a portion of the uneven web ofstock passing around said main cylinder, which stock is returned to themain cylinder to be again recorded by the same or another worker. Such amain cylinder or swift is driven from fifty to one hundred andtwenty-five times faster in surface sp'eed then the wor ers orcarding-rolls and it is necessary to run the main cylinder at avery-high speed, say from fifteen thousand to twenty five thousandinches per minute, according to the nature or" the stock to be carded,the finer thestock the greater the speed, be

cause all the carding is done by said main cylinder and said workers,the speed of the workers being from seventy five to two hundred surfaceinches net minute. This great diii'erence in the speed of the maincylinder and workers causes a breaking of the fibers, insufficientcarding and loss of production, creates bunches, flyings and waste,increases the cost of the yarn and makes what is known as tender yarn oryarn of less strength. r

The object of my invention is to provide for carding all kinds offibrous materials by a plurality of pairs of slowly operatingcardclothed rolls arranged in lines between the usual feeding" devicesand dofier and its, comb or other means for removing the carded stockfrom the carding engine. These rolls are preferably arranged in threehorizontal tiers, the to and bottom rolls or rolls of the top and ottomtiers being each arranged in an angle between two adjacent rolls(hereinafter for distinction celled cylinders) of the middle tier end incarding relation with one and in stripping relation with the otherotsoid adjacentcylinders, said top and bottorn'rolls not return mg thestock removed by themto the some cylinder from which it reinoved nntilsaid stock has recarded by a roll of the other tier. l

By arranging two cylinders with their teeth point to back with eachother and operating them at a surface speed of about two thousand tothree thousand surface nches per minute and arranging a roll above, inthe angle between the two and another roll in the lower angle betweenthe two, each a 1 roll being in working relation with both cylinders andeech roll. stripping one cylinder and carding with the other cylinder,the relation of said rolls to the same cylinder being reversed, I havefound that i could work any fibrous web so as to make an even blend ofitproviding I nsedtwo sets of these cylinders and rolls, which sets ofcylinders are'not in speed relation to each other, that is, the speed ofone set is not determined by the speed of the other. This isaccomplished by arranging between said two sets e conveyer cylinderwhich revolves in the same direction with first cylinder of the secondset and in the opposite direction to the second cylinder of the firstset. This conveyor cylinder permits any desired speed to be maintainedfor either the first or second set independently ot the speed of theother set so that the stock thesis not properly carded on the first 2'ieedingdn set on reaching the second or feeding-out set me again bereturned to the second or first cy inder of the first set to passthrough the same processnpreviously described.

1 do not limit myself to the use of two sets of cylinders anda conveyorcylinder, be-

cause three or more sets may be used with. a conveyor cylinder betweeneach set and the following set, but It have found that twosuch sets usedwith therolls and the other cylinders herein shown and described aresnfici'ent for practical purposes and occlipy no greater door-space thanthe ordinary carding engine in which a main cylinder and workers areemployed. In the accompenyi IS a diagrammatic representation ns deelevation of the rolls and cylinders of a cardng drawing the figure derin carding relation with the second of veyer cylinder.

laden with the last cylinder of the first set I claim as my invention 1.In a carding engine, the combination of two feeding-in cylinders, aconveyer cylinder in carding relation with the second of the feeding-incylinders and two feedingout cylinders in stripping relation with eachother, the first of said feeding-out cylinders being'in strippingrelation with said con- In a carding engine, the combination of twofeeding-in cylinders, a roll arranged in an angle between saidfeeding-in cylinders and in carding relation with the second of saidcylinders and in stripping relation with the first of said cylinders,a'conveyer cylinder in carding relation with the second feeding-incylinder and two feeding-out cylinders, the first of which is instripping relation with said conveyer cylinder and with the second ofsaid feeding-out cylinders, and a roll arranged in the angle betweensaid feeding-out cylinders and in carding relation with the second ofsaid feeding-out cylinders and in stripping relatdion with the first ofsaid feeding-out cyliners.

3. In a carding engine, the combination of a set of feeding-incylinders, a set of feeding-outicylinders, a conveyor cylinder arrangedbetween said sets and in carding relation with the last cylinder of thefirst set and in stripping relation with the first cylinder of thesecond set, the speed of each set being independent of the speed of theother set.

4. In a carding engine, the combination of two feeding-1n cylinders, aconveyei cyhnthe feeding-in cylinde s, two "feeding-out cylinders instripping relation with each other, the first of said feeding-outcylinders being in stripping relation with said conveyer cylinder, androlls arranged in the angles between said feeding-in cylinders above andbelow, each roll being in carding relation with one of said cylindersand stripping relation to the other of said cylink ders and the relationof said rolls to the same cylinder being reversed.

5. In a carding engine, the combination of a set of feeding-incylinders, a set of feeding-out cylinders, a conveyer cylinder lirrangedbetween said sets'and in carding flieand in stripping relation with thefirst cylinder of the second set and rolls arranged above and below inthe angles between the cylinders of each set, each roll being in card-)in relation D .conveyer-cylinder arranged ing relation with one of thecylinders and in stripping relation with the other cylinder of thecorresponding set and the relation of I said rolls to the same cylinderbeing reversed.

6. In a cardin engine, the combination of a set of feeding-in cylinders,a set of feeding-out cylinders, a conveyer cylinder arranged betweensaid sets and in carding relation with the last cylinder of the firstset and in stripping relation with. the first cylinder of the secondset, rolls arranged above and below in the angles between the cylindersof each set, each roll being in carding relation with one of thecylinders and in stripping relation with the other cylinder of thecorresponding set and the relation of said rolls to the' same cylinderbeing reversed and transfer rolls.

7. In a carding engine, the combination with feeding and dofiing devicesof a set of feeding-in cylinders, a set of feeding-out cylinders, aconveyer cylinder arranged between said sets and in carding relationwith the last cylinder of the first set and in stripping relation withthe first cylinder of the second set, rolls arranged above and below inthe angles between the cylinders of each set, each roll being in cardingrelation with one of: the cylinders and in stripping relation with theother cylinder of the corresponding set and the relation of said rollsto the same cylinder being reversed and transfer rolls.

8. In a carding engine, the combination with feeding and dottingdevices, of a feeding-cylinder, a feeding-out cylinder, aconyeyer-cylinder arranged between said first named cylinders, and incarding relation with said feeding-in cylinder and in strip pingrelation with said feeding-out cylinder, and rolls arranged in theangles between said cylinders, each roll being in stripwith saidconveyer-cylinder.

9. In a carding engine, the combination with feeding and dofiin devices,of a feeding-in cylinder, a fee ingout cylinder, a between said firstnamed cylinders and in carding'relation with said feeding-in cylinderand in stripping relation with said feeding-out cylinder, a fancy-rollin operative relation with said feeding-in cylinder and a carding rollarranged in the angle between said conveyer roll and said feeding-outcylinder and in carding relation. with the conveyer-cylinder and instripping relation with the feedingout cylinder.

In witness whereof, I have afllxed mysignature in presence of twowitnesses.
